hi,
maybe some of you can be intrested in my evaluation on special parts on my Seeeley Commando:
Note: I don't wish to have the fasted road going on the world, but I wish power and most of all REALIBILITY
I ride 10.000 kms the year, only on public roads, with the Seeley, mostly between 4.500 and 6.500 RPM, I don't own a Seeley to hold it at max 3.000 RPM.
Of course I did not made this changes at once, my experience is that if you wish to gain power and realibility, you need to do more as rising the CR and put a other camshaft, if you don't wish to have engine salad on the tarmac you will need to change almost all the parts and pray the Lord every time you rev up
Also don't believe that you will gain 10 HP with changing only a few parts, the most of the time you only move the power band. HP are so difficult to find...
They main tink is to find a harmony between all this different parts.
Every time I broke some parts on my engine, I replace it with higher quality, with as end result that the engine only look like a Commando at the moment and don't ask me how mutch $ I spend,
I stop counting at 25.000 $ and I still don't reach the end at the moment, It is like a drug, I will never stop.
Don't think that I am Rockefeller, I have to work very hard for every cent I spend.
You will see that my evaluation are very high, but keep in mind that I try cheep parts before, and was not satisfied
The rule is: cheep can be very expensive
The frame:
It is a Seeley MK 3 replica made by Roger Titchmarch: No: 008
It is amasing how you can make sutch a light frame with a fantastic road holding with only a few Reynolds 531 tubing, great design M. Collin Seeley!
I put the footrest 2.5 cms lower for more confort,when you are cornering hard you will tuch your boots on the ground, that will say: time to keep it safe...
The forks are shortened Commando's, front brake is the kit from RGM, triple trees are from Minnovation, shock absorbers are from Ohlins, half top fairing is a Commando PR, tires are Bridgestone Batlax 45, I own two fuel tanks, the original with 2.5 gallons and the Manks version with 4 gallons.
My comments: fantastic road holding, forgive every mistake from the rider, the bike is light and low and is a real beauty.
Evaluation 10/10
The gearbox:
It is a TTI 5 speed road model, with almost 50.000 kms, never have a problem! The first gear is a bit longer as the original Commando, so the four other gears are closer, very fun to play with it and keep the rev's high in every corner.
I put a longer foulded kick starter on it, more nice as the original one
Evaluation 10/10
The engine:
The crank:
The last change I made is the crank from JS motorsport , a billet one piece steel crank, a piece of mecanical art. Same weight as the original
I have only 3.000 kms with the crank, so far my evaluation :10/10
The rods and pistons:
Longer Carillo's rods from JS Motorsport with high compression lightweight pistons, I keep the CR at 9.8 / 1, this winter I will go for 10.5/1. The pistons are 100 grams lighter each as the Maney's
It is true that you have almost no vibes any more, the engine is runing so smooth now.
I put the rod's and pistons togheter with the JS crank, so far my evaluation 10/10
The valve train:
The entire valve train is from JS, valves are original sizes, the camshaft is a JS stage 2 B, with the beehive valve springs and lighter puchers, I feel so confident now when I rev up.
Between 4.500 and 6.500 it is like you put the post combustion on it
The sound is like a partition from Beetoven with the Maney's two in one exhaust, the song of joy for a vertical twin!
Evaluation after 6.000 kms: 10/10
The crankcases:
Steve Maney of course, It will never broke I think, when I broke the original crank, there was a light crack in the cases, the welder says: good quality of the alloy.
Never a oil leak or any problem at all, just keep a eye on the camshaft bushing.
Evaluation 9 /10 becouse of the camshaft bushings.
The cylinder:
Steve Maney aluminium, put it on your engine and forget it, to me the sleeves are soft, with more as 50.000 kms I have to change the sleeves once, I plan to give the sleeves a surface treatment like Nicasil this winter.
Evaluation 10/10
The head:
Fullauto what else, the mecanical perfection, no porosity, no oil leaks, powerfull even with original valves sizes, I plan to ship the head to Jim Comnoz this winter for bigger valves and flowing
I am using the original head gasket with a squish at 1.7 mm.
I buy the head from CNW
Evaluation 15/10
The carbs and manifold:
Keihin FCR 35 mm fro Matt from CNW I have this carbs almost 50.000 kms. They arrive with a way to ritch setting, and believe me it is not easy to find the good setting, so many ways to change
the setting: main jet, pilot jet, main air jet, pilot air jet, pilot air screw, pilot fuel screw lot of needels and so on. maybe the original setting was good for a stock engine but not for mine.
It take me a lot of time to find the good setting, but when you gat it: wonderfull, no flat spot at all, no problems with starting
Keep a eye on the needel tube, when at once you are to ritch around 4.500 RPM, put new tubes and problem solved.
Two evaluation:
Setting even with a dyno, difficult! 7/10
Power: 10:10
The ignition:
Tri Spark MK 2, very good, before I was using a Tri Spark MK1 and it broke two times, so I go to Pazon, and was very satsified, the day that Tri Spark was there with the MK 2, I give them a second chance, and I can tell you the MK 2 is amazing, I use the coil from CNW and I never have to give two kicks to start the engine, some time I put the kick slowly down to find the compression and the engine start! The setting is 28 degrees.
Evaluation:
Tri Spark MK 1: 2/10
Pazon/ 9/10
Tri Sark MK 2: 10/10
The Exhaust:
Maney two in one, powerfull, a must to have, I have to make two new headers becouse the original broke, the new one are stainless and sleeved at the head. Keep in mind that the Maney was not made for a Seeley frame, and you have to made some changes to fit it.
But what a sound...
Evaluation 9/10
Alternator:
Sparks tri phases, very good, only the wires brokes at the stator, but you can repare it.
Evaluation 8/10
So, I forgot a lot of other parts I think. Feel free to ask me for more details
I wish to thanks some persons , like Franky Jordens the britsh bike spacialist here in Belgium,
Matt from CNW, Jim Smidt from JS motorsport, Jim Comnoz, Bert Smet and many others, without them, no Seeley!
